Ummmmm is that the question or is there other numbers
Answer:
Not sure but 2 would be the same as 1 so 39.5 and 3 and 4 would be 50.5
Step-by-step explanation:
1 and 3 make a right angle and so does 4 and 2 so all I did was subtract 39.5 from 90 since a right angle=90 degrees
This is a neat little question. I don't think I've seen it before.
Step one
=======
Find c
3^2 + 4^2 = c^2
9 + 16 = c^2
c^2 = 25
c = 5
Step 2
====
Set up your first equation for b^2
a^2 + 4^2 = b^2 from triangle XWY
Step 3
=====
Set up your second equation for b^2
25 +b^2 = (a + 3)^2 from triangle XWZ
Step 4
=====
Put the results of Step 2 into step 3 and solve
25 + a^2 + 16 = (a + 3)^2 Collect the like terms on the left.
41 + a^2 = (a + 3)^2 Expand the brackets on the right
41 + a^2 = a^2 + 6a + 9 Transfer the 9 to the left.
32 + a^2 = a^2 + 6a Subtract a^2 from both sides.
6a = 32 Divide by 6
a = 32 / 6
a = 5 2/6
a = 5 1/3
